1. General Function
The PH-GT10 circuit card provides the TSW I/O bus interface allowing the CPU board to control the TSW,
HSW, and PLO cards in the Inter-node Switch Module (ISWM) of the ISW/CMG. This circuit card also is
equipped with the copy function to be consistent with the data of TSW I/O bus in both systems (single/
dual). This circuit card is used for the IPX-U/IPX-UMG system.
